I have installed it this way:
- Run the installer, choose install directory D:\OneDrive\Documenten\BredaWiki. Stop the services
- Run the installer again, choose a different install directory, eg. D:\OneDrive\Documenten\wiki2. Stop the services.
Now, if you want to start the mediawiki on D:.....\BredaWiki, open the file explorer and go to that folder, run
manager-windows.exe that is on that folder and start the services.
If you want to start the mediawiki on D:...\wiki2, stop first the Bredawiki one, and then run manager-windows.exe that is in the wiki2 folder.
